Abstract
Combustion engine power plant related technologies play a
significant role in the energy industry. Today, global
challenge over whole energy field is to reduce greenhouse
gas emissions to combat climate change. This can be
achieved by increasing energy efficiency, and by finding
alternative and renewable options instead of conventional
fossil energy sources.
Work on fuel flexibility was conducted within the Future
Combustion Engine Power Plant programme (FCEP) of the
Cluster of Energy and Environment (CLEEN) in Finland. A
number of fuel options, including challenging liquid
biofuels and their treatment, as well as gaseous fuels,
were explored for different engine concepts. LNG was
found to be potential solution to oncoming environmental
requirements in shipping. Biogas was studied as regards
upgrading technologies, particularly siloxane removal,
which is a weak spot for biogas from wastewater and
landfills. Mediumspeed engine was tested by using
different fuels. Some of the fuels were challenging, and
therefore pre-treatment methods for difficult fuels were
developed to enable their use in medium-speed engines.
Combustion properties of various fuels were studied with
special ignition test unit, with a medium-speed and with
a high-speed engine. Some fuels yielded promising results
when engine performance and emissions are considered. A
special task devoted to development of a diesel-ignited
dual fuel ethanol high-speed engine for non-road
machinery. The developed engine can be switched from
diesel to diesel-ethanol operation at any load without
noticeable change in engine operating point.
Work on fuel flexibility within the FCEP programme took
steps towards increased fuel flexibility, and
consequently, towards better energy security in Finland.
In addition, the demand for lower environmental impact of
the current combustion engines was sought for. The
structure and form of FCEP programme supported close
cooperation of the industrial and research partners. This
kind of cooperation and further development in the field
of fuel flexibility is still needed.
